toro recycler model 20017 over-revving

Recently, I replaced the carburetor on this lawn mower and now it starts fine but is over-revving a lot. I made sure the linkages are good and they seem to be.The only thing is that the governor arm is tilted to the right because the governor link is too long that it forces the arm right (the whole arm is tilted, not just the upper part, it is still 90 degrees), so to make up for this extra tension on the throttle spring, i bent the tab slightly right. Now the the spring is looser an yet the mower is over-revving the same amount. Did i do something wrong? Also, does the angle of the arm affect the speed despite the tension of the spring?

Here is a link that might be useful: linkages

Did you adjust the governor arm with the throttle fully open. Off hand, I'm not sure which was it goes, but move the arm to make the throttle full open and after loosening the screw, turn the governor part either fully left or right. You'll know which way is the right way. Tighten the screw. The linkages look right.
